Of the approximately 380 families of angiosperms, representatives of only 10 are known to form symbiotic associations with nitrogen-fixing bacteria in root nodules. The morphologically based… Expand
Generic relationships within and between the gymnosperm families Podocarpaceae and Phyllocladaceae based on an analysis of the chloroplast gene rbcL.
Analysis of sequences of the chloroplast gene rbcL for 76 taxa of Podocarpaceae (representing all genera except Parasitaxus) and five species of Phyllocladaceae were undertaken with respect to their… Expand
The presence of an RHD pseudogene containing a 37 base pair duplication and a nonsense mutation in africans with the Rh D-negative blood group phenotype.
Antigens of the Rh blood group system are encoded by 2 homologous genes, RHD and RHCE, that produce 2 red cell membrane proteins. The D-negative phenotype is considered to result, almost invariably,… Expand
Using Sequences of rbcL to Study Phylogeny and Biogeography of Nothofagus Species
Sequences of rbcL for 23 species of Nothofagus and three of Fagus have been determined and analysed to form phylogenetic trees. The two genera are well separated. The species of Nothofagus separate… Expand
The complete amino acid sequence of the human erythrocyte membrane anion-transport protein deduced from the cDNA sequence.
1. We have isolated cDNA clones corresponding to the red cell membrane anion-transport protein (Band 3). 2. The cDNA clones cover 3475 bases of the mRNA and contain the entire protein-coding region,… Expand

Antigens of the Rh blood group system are encoded by 2 homologous genes, RHD and RHCE , that produce 2 red cell membrane proteins. The D-negative phenotype is considered to result, almost invariably,… Expand
rbcL and Legume Phylogeny, with Particular Reference to Phaseoleae, Millettieae, and Allies
A parsimony analysis was conducted on 319 rbcL sequences, comprising 242 from 194 genera of Leguminosae and 77 from other families. Results support earlier conclusions from rbcL and other molecular… Expand
Prediction of fetal D status from maternal plasma: introduction of a new noninvasive fetal RHD genotyping service
BACKGROUND : Invasive procedures to obtain fetal DNA for prenatal blood grouping present a risk to the fetus. During pregnancy, cell‐free fetal DNA is present in maternal blood. The detection of RHD… Expand
Fetal blood group genotyping from DNA from maternal plasma: an important advance in the management and prevention of haemolytic disease of the fetus and newborn
The cloning of blood group genes and subsequent identification of the molecular bases of blood group polymorphisms has made it possible to predict blood group phenotypes from DNA with a reasonable… Expand

Abstract Root tips of 12 species of higher plants have been analysed to measure DNA per cell, which showed a tenfold variation, and RNA per cell, which showed a fivefold variation. Average nucleolar… Expand
